I voted today, election day.

I usually vote in the evenings, but today I tried voting in the afternoon. There were unexpected differences!

Tomorrow's NASA Astronomy Picture Of the Day (APOD): baby solar system HH 30.

ESA/Webb, NASA & CSA, Tazaki et al.

A close-in image of a protoplanetary disc around a newly formed star. Many different wavelengths of light are combined and represented by separate and various colours. A dark line across the centre is the disc, corresponding to the densest parts of the disc, made of opaque dust: the star is hidden in here and creates a strong glow in the centre. A band going straight up is a jet, while other outflows above and below the disc, and a tail coming off to one side

This is the closest photo of Saturn ever taken.
🔭 🧪

This is the closest image of Saturn ever captured by the Cassini spacecraft. It shows the planet in a majestic and serene light, with its rings in the foreground. The planet's golden hues are highlighted by the sunlight filtering through its upper atmosphere. A notable feature is the intriguing hexagonal storm at the north pole, a unique weather phenomenon in our solar system. The image provides an unparalleled, close-up perspective, inviting viewers to appreciate the intricate details of Saturn's cloud bands and the sheer vastness of its ring system. It is a stunning portrayal of the beauty and complexity of this gas giant, captured from a vantage point closer than any human-made probe has ventured before.

This is the clearest photo ever taken of Venus.
🔭 🧪

This is a cropped, close-up image of the planet Venus, taken by the Parker Solar Probe’s WISPR instrument. The image shows a crescent Venus against the black backdrop of space, with the edge of the planetary limb clearly defined. The crescent is illuminated by sunlight, transitioning from a bright, almost white glow at the top right edge to a subtle, golden yellow that dominates the majority of the illuminated area, before fading into the darkness of the planet's night side at the bottom left. The distinct variations in brightness and texture across the crescent suggest cloud formations or atmospheric layers. A bright, flaring light source is visible at the top right corner, likely the Sun, which contributes to the illumination of the crescent. The overall composition emphasizes the stark contrast between the luminous crescent and the surrounding darkness, highlighting the curvature and celestial context of Venus.

Tomorrow's NASA's Astronomy Picture Of the Day (APOD): colliding spiral galaxies by JWSTand Hubble.
🔭 🧪

Two spiral galaxies take up almost the entire view and appear to be overlapping. The galaxy at left, IC 2163, is smaller and more compact than the galaxy at right, NGC 2207. The black background of space is dotted with foreground stars and extremely distant galaxies.

High resolution image of a heavy star.
🔭 🧪

$The luminous, hot star Wolf-Rayet 124 (WR 124) is prominent at the centre of the James Webb Space Telescope’s composite image combining near-infrared and mid-infrared wavelengths of light. The star displays the characteristic diffraction spikes of Webb’s Near-infrared Camera (NIRCam), caused by the physical structure of the telescope itself. NIRCam effectively balances the brightness of the star with the fainter gas and dust surrounding it, while Webb’s Mid-Infrared Instrument (MIRI) reveals the nebula’s structure. Background stars and galaxies populate the field of view and peek through the nebula of gas and dust that has been ejected from the ageing massive star. A history of the star’s past episodes of mass loss can be read in the nebula’s structure. Rather than smooth shells, the nebula is formed from random, asymmetric ejections. Bright clumps of gas and dust appear like tadpoles swimming toward the star, their tails streaming out behind them, blown back by the stellar wind.$

The Tarantula Nebula, also known as NGC 2070, is a star-forming region located in the Large Magellanic Cloud. This image, captured by the James Webb Space Telescope's Near-Infrared Camera (NIRCam), showcases the nebula's intricate structure and vibrant colors. Red hues indicate the presence of hot, ionized hydrogen gas, while blue areas reveal cooler dust and gas.

V838.
Each color shows the passage of time. As the bright flash of light left the star, it illuminated the dust surrounding it, but because space is so big, we actually see the light travelling and illuminating the dust as it goes along.

This image, captured by NASA's Galileo spacecraft in 1996, showcases Io as a crescent shape against the backdrop of space. A prominent blue plume erupts from the dark side of the moon, originating from the Ra Patera volcano. This volcanic activity is a defining characteristic of Io, a moon known for its intense geological activity and dynamic surface.

Hubble's View of Jupiter and Europa in August 2020.
🔭 🧪

This latest image of Jupiter, taken by the NASA/ESA Hubble Space Telescope on 25 August 2020, was captured when the planet was 653 million kilometres from Earth. Hubble’s sharp view is giving researchers an updated weather report on the monster planet’s turbulent atmosphere, including a remarkable new storm brewing, and a cousin of the Great Red Spot changing colour — again. The new image also features Jupiter’s icy moon Europa.

DAMMIT NPR.

I spent nine months upgrading over TEN THOUSAND desktops at a F500 client. The grand total was over SEVENTY THOUSAND applications upgraded.

Y2K "didn't live up to the hype" because the industry busted ass to duct tape everything first.

NPR @npr.org · Dec 28

People feared the computer glitch would mean "the end of the world as we know it." Thankfully, Y2K didn't live up to the hype after years and billions of dollars were spent on painstaking preparation.

Y2K seems like a joke now, but in 1999 people were really freaking out
